    Abstract: This system and method for producing nanomaterials allows for the production of relatively high concentrations of nanoparticles with a minimum of expense, time and energy. Ultrasonic waves, produced at a power of approximately 50 W with a frequency of 26.23 kHz, are projected on a material sample while, simultaneously, a fluid stream jet is projected on the material sample. The ultrasonic waves, in the presence of the fluid jet, create cavities that explode at the surface of the solid material, leading to creation of cracks in the material surface. With the increase in the number of cracks in the material, the solid material erodes. The eroded material, which is on the nanometer scale, is collected on a suitable substrate, such as silicon. This method allows for the preparation of nanoparticles from any solid material, in particular very hard materials, such as diamond, silicon carbide and the like.

  • Patent number: 8132746
    Abstract: A method of exfoliating a layered material to produce separated nano-scaled platelets having a thickness smaller than 100 nm. The method comprises: (a) providing a graphite intercalation compound comprising a layered graphite containing expandable species residing in an interlayer space of the layered graphite; (b) exposing the graphite intercalation compound to an exfoliation temperature lower than 650° C. for a duration of time sufficient to at least partially exfoliate the layered graphite without incurring a significant level of oxidation; and (c) subjecting the at least partially exfoliated graphite to a mechanical shearing treatment to produce separated platelets. The method can further include a step of dispersing the platelets in a polymer or monomer solution or suspension as a precursor step to nanocomposite fabrication.

  • Patent number: 8125129
    Abstract: The invention relates to working electrode for an electrodynamic fragmenting installation. The working electrode comprises an insulator (1) with a central conductor (2), which axially passes through the insulator (1) and carries at its working end an electrode tip (3) which is formed by an exchangeable changing part (4) and adjoins a stop area (6) of the central conductor (2) with a contact area (5) under axial compressive prestress. The invention makes it possible to provide working electrodes for electrodynamic fragmenting installations in which the electrode tips can be exchanged in a simple manner and which can be operated practically without maintenance over a long period of time even in case of great pressure pulsations.

  • Patent number: 8070078
    Abstract: A method and an apparatus for crushing material, particularly mined material, are disclosed. In one embodiment two or more pairs of crushing rolls successively crush mined material. The pairs of crushing rolls are arranged and operated so that an upstream pair of rolls produces a feed, preferably a pressurized feed, for a downstream pair of rolls. In another embodiment, at least an upstream pair of rolls is driven intermittently, for example, by means of a stepping motor to provide stepped rotational movement of the rolls.

  • Patent number: 8066794
    Abstract: One aspect is a method of recovering minerals. The method includes heating aggregated minerals with microwave energy. The aggregated minerals consists of at least a first and a second mineral bound together, the first and second minerals each having different differential thermal expansion rates such that fractures occur between the minerals of the aggregated minerals. The fractured minerals are subjected to microwave heating to induce fractures between and separation of the at least first and second minerals, and also to ultrasound energy causing further size reduction. The fractured and size-reduced minerals are heated with microwave energy. The fractured and size-reduced minerals consist of metal-containing materials, such that metal-containing materials are heated to at least the melting temperature of one of the metals in the metal-containing materials.

  • Patent number: 8025248
    Abstract: The invention is a detachable “blade foil” system for comminuting machines which employ a rotating turbine. The turbine blades are each endowed with a detachable leading edge which is shaped in an air foil configuration. These “blade foils” are penetrated by a vent chamber having an inlet port and an outlet port. The vent chambers aid in drying input material that is processed by a comminuting machine and also aid in reducing sound from the turbine. The configuration of the inventive blade foils also vary to aid in material drying. The configuration of the blade foils also define the level of particle size attributed to the processed output material. Hence by selecting particular blade foil configurations the operator can achieve different levels of material drying and differing output particle sizings.
